 First Test Labs for Next-Generation Internet Protocol (IPv6) Are Accredited  Closeup photomicrograph of rotifer B. calyciflorus (whole organism seen in upper left corner) with quantum dots assimilated from ingested ciliates appearing red.  Silver nanoswitch: when the voltage between a gold conductor (top) and silver conductor (bottom) exceeds a critical point, silver ions rapidly assemble like a lightning strike to bridge the gap through a organic molecule monolayer.  In-depth look: An image of gold atoms on tin from a state-of-the-art scanning electron microscope (left) has relatively poor depth of field - only parts of the image are in sharp focus. By contrast, the entire image from a helium ion microscope image (rig News And Events
